WINDOW AND DOOR SGREEN.

Specification 01. Letters Patent. Patented Sept. 30, 1913.

Application filed November 6, 1912. Serial No. 729,815.

' To all whom, it may concern:

Be it known that I, CHARLES H. ZIMMER- MAN, a citizen of the United .States, residing at St. Paul, in the county of Neosho, State of Kansas, have invented certain new and useful Improvements 1n Window and Door Screens; and I do hereby declare the folthe mesh. Fig. 3 is lowing to be a full, clear, and exact description of the invention, 'such as will enable others skilled in the art to which it appertains to make and .use the same.

My invention relates to improvements in window and door screens and more particu larly to those of the collapsible and adjustable type.

The primary object of. my invention is to provide a window or door screen which by reason of its novel construction, and arrangement of parts may bereadily adjusted to fit a window or door of any size within a reasonable range, and which may also be knocked down or folded in a few moments and reassembled in an equally short time.

A further object is the provision of a window screen, on which the wire screening may be put on or taken off with a minimum of time and labor.

The above and additional objects are accomplished by such means as are shown in the accompanying drawings, described. in the following specification and then more particularly pointed out in the appended claim.

In the drawings: Figure 1 is a perspective View of the device. Fig. 2 is a top plan view thereof folded partly as in applying a cross sectional view.

' Fig. 4 is a detail perspective of one joint.

Referring to the drawings throughout which like numerals designate similar parts, the screen frame proper is shown as comprising four right angular sections 1 and 2. This frame may be constructed of any material, though preferably of wood such as is used in the manufacture of the ordinary screen frame but somewhat heavier.

The numerals 3, 4, 5 and 6 designate the points of disposition of the novel joint. As shown in the drawings these joints are positioned one at each middlepoint of the several sides of the frame. In these joints, the tongues .7 and 8 carried by and integral with each of the frame sections 1, intermesh with the tongues 9 and 10 carried by and integral with the other frame sections 2. These tongues are beveled as at 11 on their longitudinal edges and are straight at their free or inner edges as at 12 to permit pivotal movement of the sections but form stops to limit the closing of the sections and provide tight joints to prevent the passage of water therethrough.

In assembling the frame, the sections 1 intermesh with the tongues of the sections 2 and are held in assembled position by transversely extending pins 13 forming pivots seated through transverse bores 14, which are providedin corresponding series throughout the length of the several tongues. A button stop member 15 is pivotally secured to the rear face of each of the more'centrally disposed tongues 7 to be moved in alinement therewith when the the tongues of parts are'being pivoted but to lie trans:

versely of the tongues to arrest the pivoted section 9 and prevent the same swinging too far. This joint as described above is applied to the middle portions of each side of the frame.

The numeral 16 indicates the outwardly slanting wire holding spikes which are provided at spaced intervals along one face of the frame, being carried upon the several sections thereof for attachment of the wire mesh 17 by turning the raw edges thereof This mesh is attachable and removable by pivoting the four (4:) sections as shown in Fig. 2 of the drawings.

It will be seen that a screen made in accordance with the above description may be readily collapsed by merely removing the wire screening from the spikes 16, and extracting the pins 13 and turning the buttons 15.

It is also apparent that'having disintegrated my frame it is possible to adjust it to fit windows of varying size by sawing segments of equal length off the ends of the several tongues. A jointed brace connects the sides of the frame and consists of two pivoted sections 19 provided with apertures 20 engaged by pins 21 while sharp pins 22 extend from the ends of the sections to pierce the frame and hold the brace in position.

Having thus described my invention, what I claim is:

A screen including a collapsible and adjustable frame, and a screening member detachably secured thereto, said frame being provided with a plurality of locking joints having a transverse bore, said joints comprising to form hems 18.

a plurality of intermeshing tongues carried In testimony whereof, I afiix my signa- Ey thef' extiellndities oftle several frame ture, in presence of two Witnesses.

ers 0r 0 mg sai joints in assem e osition, a button stop carried on the under- CHARLES ZIMMERMAN' 5 ace of one of the tongue members, and a Witnesses:

pin seated in said bore to pivotally connect ANTHONY WARNER, the parts. 0. E. FREIRLE.
